Application, filed Septcmlierf, Serial ite. -effr To all 'ti/hom 'it mayconcern:

Be it known that I, RoewnLL H. BUCKING- Hair, a citizen of the UnitedStates, residing at Barberton, in the countyof Summitand State of Ohio,have invented certain new' and useful Improvements in `Removeble-RinilVheels, of which the following is a` specifi--V cation, referencebeinghad to the acczoui-l panying drawings.

My invention relates to wheels with re-A movable rims, particularly toWheels of that'` description adapted for use in self-propelled vehicles.As is well known in `self-propelled vehiclesl as Well as'less vcommonlyin other vehicles, Wheels with resilient tires are used,

and these tires are liable to injury from puncture or tearing or fromthe ordinary 'Wearfand tear ofthe runningfof the vehicle,

and, have ,tofe'removed an replaced by4 other tires. It isoffcoursedesirable that the tires thus injured should be able to be removed andnew tires put in their place as readily and as speedily as possible, andmany devices intending to accomplish that end have'been constructed. i,

In my invention, instead of liaving'the elastic tire .only removed fromthe Wheel, I remove the tire' and rim toI whiclijfitis ettafched, and itis'tlie'. object of-my invention to provideV a new and,4 improved `formof wheel in which the'resilient, tire andrim .nay be both readilyremoved together, and anew tire' and rim readily. and speedily placedupon the Wheel, .zmd"1nnly locked imposition so that the rimandtiljecan-not be :accidentally removedbut at Athe same ,time maybcjreadil-y removed Whenever dei-1y sired. I accomplish 'thief-objectesillusf trated in the drawings,- endll as hereina-er described. l y 4Whitt I regard as new isset forthin the claims'. Q l.'

sleeves 12 are preferably 'flattened upon one` surface, as is best shownin Fig. 3, to a'ord and are .provided each with n stud or pin 13 1:4indicates a, bearing ring,pre'ferably of metal which is seated upon oneof the langes-'7,`bearing upon the'externel periphv'ery 'oi said dange,'and is rigidly held-in Yspokes 8 are adapted to titclosely end snuglywithin the sleeves 12, so that there will not/ -r :i bearing for theparts hereinafter described',

pleine either by fastening it to the spokes 8,

or 1n any suitable manner. The bearing ring le is provided with n.circumferential flange 15, located upon the cuter edge otitis periliery, a Suitable Idistance sway from the spo es. 16 indicates enoperating ring, Winch 1s rotatably mounted upon the bearing ring 14;,

bearing` against the innersurfece of the Harige 15.v The inner surtaceof the operatin rind 16 is nrovided with e number of' g b J.

cam slots 1-7, best shown .in Fig 4, Which equal in number the number ofspokes, and

are adapted to register Withand engage the studs 131 lt will be obviousthat when the operating ring le is rotated, the engagement oitl the camslots 1 7 with the studs 13 Will cause the sleeves 1Q to simultaneouslymove radially either inward or outward from their original position,according to their position in the slot and the direction of rotation ofthe operating ring 16. The.. slots, as is best shown m Figs. 2 and 4,are in the form of recesses eutonly partly through the operating ring16, and from the inner surface, in order to protest the parts againstdirt and prevent the slots 1T from being iilled with dust and dirt. L

18 indicates protecting ring Which :is mounted uponthe periphery of thebearing ring` 14: and rigidly held thereon in any suit able manner, itsouter surface bearing against the inner surtace of the operating ring 16so that the said operating ring rotates between the flange and the saidprotecting ring. The protecting ring 18 is provided with a plurality otradially located slots 19 through which the studs 13 pass. .heseopenings 19 are of sntlicient length to permit. a. sullicient radialmovement in- 'ard and outward ot the sleeves 12 to engage and disengagetheir ends from the sockets 11. The object ot the protecting 'ring 1Sisto cover the slots 17 onthe operating ring 1G from the inside, so asto prevent the entrance of dirt. 'lhis will be readily seen trom Fig. 3Where the" relative position of the several slots is best shown. In thisiigure, aswill be seen, the slots 19 in the'ring 18 are n'arroiverthanthe flattened portion ot the sleeves' 12 against which the ringbears, and thefsides ot the ring 1S cover the cam slots 1i', so as topreventA the entrance ot dirt. l

20 indicatesa bolt which, passing through the various parts, may beturned to lock them firmly together', andpreventing the rotation et theoperating ring 1S, Will prevent the accidental separation ot' the rimand the Wheel, vv-hile by loosening the bolt the part may be turned. Thecam slots themselves are so shaped, as will be seen from Figs. .l and4t, that when the wheel is put together for use, any pressure exertedradially along the spokes will not tend by the engagement 'of the' pinWith the cam slot to rotate the ring and separate the parts.

The operation of this device will be readily understood. lVhen it isdesired to remove the rim, the operating'ring, by means et any suitabletool, as by a spanner, applied to the pins, 21,. is rotated from left toright in Fig, 1. This movement Will cause the `sleeves 12 to movesimultaneously radially invvard, freeing their ends from engagement withthe sockets 11. The rim, oi' course, is then removed trom the Wheel anda nevi7 rim and tire put in position, the operating ring then beingrota/ted from right to left in Fig. 1', throwing all the sleevesradially outvvard into engagement with the sockets. "The parts are thenlocked by the .bolt 20, and the Wheel is in condition for use.

I haVe'shOWn my Whee'las constructed with only eight spokes,v which-` ofcourse, is only for the convenience of illustration, `as any number maybe used. I have also shown it witha resilient tire of the ordinarypneumatic outer and inner tube type, but of course any form of tire maybe used, as may be preferred.
